(01. 131-196) a combination tobacco compartment and, bowl housing which is chambered in such a manner as to provide more efiectively a circulation of air to cool the bowl and smoke.

A further object of the invention resides in providing an improved stem wherethrough the smoke from the bowl is caused to traverse a redouble'd path in order to more effectively treat the indrawn smoke from a cooling standpoint.

Astill further object of the invention is to provide a bowl housing, the sump portion of which is detachable in adownward direction and wherein the residue is segregated from the smoke which is later drawn into the mouth.

Yet a further object of the invention is to provide an improved insulated bowl whereby the heat from the burning tobaccois morereadily dissipated and-radiated and a much cooler smoke is provided for the'individuals taste.-

Still further objectsresideinthe provision of a more sanitary smokers article, readilydisassembled for cleaning purposes, more healthful, and unusually attractive and appealing-as a mans smoking article;

'Still other objects, featureaandadvantages of invention will hereinafter appear;

In the drawing wherein is shown a preferred embodiment of the invention as now reduced to practice'and being sold in the trade.

Fig. 1 is a plan view,

Fig. 2 is a longitudinal mid-section,

Fig. 3 is a perspective View of one of the bowl parts,

Fig. 4 is a view partly inside elevation and partly in longitudinal mid-section of an auxiliary tip attachment for the pipe stem when :used as a cigarette holder, and

Fig. .5 is a longitudinal mid-section of the combined pipestem and tip or cigarette holder.

Referring in detail to the drawing, the invention comprises in general an upper and outer bowl housing 6, a lower and outer bowl housing 1 unscrewable downwardly (as viewed in Fig. 2) from said upper bowl 6, a pipe and stem union 8 having a reduced threaded end portion 9 screwed into said upper bowl at .a point adjacent its mouth, and a pipe-stem l9, including a bit H, screwed into saidunion.

Bowl 6 hasrsteppedinterior annular concentric-walls lz and l-3-of different diameters. Bowl 1 has stepped interior'annular concentric walls 14,15, I 6, ILandlB of different diameters. The diameter of annular walls It and it of bowl I are the same as the diameter of annular wall it of bowl '6;

Where the steps occasioned bytlie junction of one annular wall of one diameter with that of an annular wall of a different diameter, there are formed horizontal ring-like shelves or ledges in each bowl.

Into the'space occasioned by the increase in diameter ofjthe'annularwall' l3 over that of annular'wall l2 and corresponding diameters It and H! of bowl 'l'is fitted in a-friction tight manner a composite cylindrical sleeve IQ. Sleeve 19 extends from ledge 20 to shelf 2 l, and in so doing its outer periphery contactswall l3, l8, and it.

Since annular wall ll is of a greater diameter than that of walls l6 and 18, which are ofrlike diameters, there is formed between the outer wall of the sleeve l9 and wall I! an annular air space 22 with which communicates a plurality of oppositely disposed, holes 23 adjacent the bottom of said space and apertures 24 adjacent the top thereof. This arrangement of air space and vent holes for the entrainment and egress of air provides a circulation of air into and from the upper portion of the lower bowl I. "Bowl' 6 has at its mouth an annularinwardly directed flange 25 against whichabuts with exact nicety the upper edge portion of a cylindrical briar bowl insert 26. Said briar bowl has an outside diameter equal to the diameter of the'annular w'all l2 and in assembling is projected upwardly through the bottom opening of bowl 6 into a workable fit therein.

However, theoutside diameter of the insert 25 is less than the inner diameter of the sleeve 19, hence throughout the length of the insert there occurs an annular air space 21 which is augmented at a point adjacent the opening 28 in the union 8 by forming in. the outer wall of the insert 26 a circumferential groove 29.

The bowl insert 26 is provided with an internal, frusto-conically shaped hollow space, the smaller endof the hollow. space being at the bottom and to the lower end and forming a bottom closure therefor is applied a saucer-like receptacle 33 which is provided with a plurality of apertures 3|. The bowl insert 26 rests upon a horizontal ring fiange 32 from which vertically extends an annular flange 33 fitted into a circumferential groove in the outer wall of said insert, with the outer face of the vertical flange flush with that face of the insert.

irectly beneath the briar insert 26 I mount an auxiliary bowl 34, see Fig. 3, having a horizontal cross wall 35 positioned about midway between the receptacle 30 and the bottom wall of the bowl 'i so as to provide two separate chambers 36 and 31. The bowl 34 is provided with an upper annular flange 38 and a like lower flange 39. In the outer edge portion of the flange 38 I provide slots 40, and in the outer edge portion of the flange 39 I provide slots 4|. Bowl 34 is also provided with a horizontal circumferential flange 42, a portion of which is extended to form a circular lip 43, the bottom portion of which rests upon the shelf 2!, and the outer edge portion of which abuts the sleeve I9.

The inner diameters of the auxiliary bowl receptacle and those of the annular flanges 38 and 38 are preferably constructed the same and are equal to the diameter of the annular wall l4. Being constructed in this manner the lower edge of the flange 39 is adapted to rest fully upon the shelf 34, and the upper edge of the flange 38 is adapted to come directly beneath the circular flange 32, so that when the lower bowl is screwed onto the upper bowl the top edge of the briar insert is urged into a close fit with the inwardly directed flange 25.

The thickness of the flanges 33 and 39 as well as a part of the wall which forms the receptacle of the bowl 34 are such that their outer walls fall well within the space provided by the annular wall 15 and the inner diameter of the sleeve 19 so that there is provided an annular space 15 communicating with the chamber 31 through the medium of slots M and an annular space '56 communicating with space 21 and" chamber 36, through the medium of slots 43.

Bowl 1 is provided with diametrically opposite apertures 47 through which outside air is entrained into chamber 31, and there are diametrically opposite apertures 38 farther up in the wall of the bowl 1 through which this entrained air egresses after passing through slots 4! into the space 43.

In this manner, the principle of thermo-syphon cooling may be said to be employed for cooling the adjacent portion of bowl 1 as has been already mentioned.

The reduced axial end portion 9 of the union 8, wherein is formed the passage 23, is externally threaded and screwed into a tapped hole formed both in the side of the bowl 6 and the sleeve l9.

The opposite end of the union 3 is enlarged to an outside diameter equal to that of the stem ID in order that the cooling fins 52 of the union may aline with the cooling fins 53 of the stern.

Into the larger endof the union 8 are formed a plurality of stepped annular concentric walls 54 and 55 which increase in diameter as they approach the open end of the union, and a portion of the annular wall 55 adjacent the end of the union is threaded in order to engage with the threads 56 which are formed on the pipe stem adjacent its bowl end. The steps occasioned by the difference in diameter of the internal walls 54 and 55, and the difference in diameter of the Wall 54 with wall 9 form stops 5! and 58 against which I abut the ends of the pipe stem 53 and the end of the cooling sleeve 59 respectively,

The difference in diameter between the annular walls 5-5 and are such that when the ends of the sleeve 59 and stem III are fitted therein in a friction-tight manner, there is formed an annular space 60 between the external wall of the sleeve and the internal diameter of the stem.

Into the bowl end of the sleeve is fitted a baffle and in the sleeve adjacent the baffie are a plurality of holes 62 through which smoke passes from the bowl to the annular space 69. The space 63 extends to an internal annular rib 63 a jacent the inner end of the pipe stem against which rib the inner end of the bit H abuts. At this point, said space 60 stops short of the mouthpiece end of the cooling sleeve. At the mouth end of the cooling sleeve are formed holes 65 in the periphery where the smoke again enters the cooling sleeve and is directed to a point adjacent the baffle 6| where it enters the mouth of the filter 65, through which it is conducted to the passage 6'! in the bit and thence into the mouth of the smoker.

The circuiting of the smoke through the holes 62 adjacent the bafile BI into the space 63, thence through the hole Giand back again to the bafile 6i where it enters the filter 66, causes the smoke to give ofi an appreciable amount of its heat due to the radiation afforded by the fins, thereby producing an inviting and cooling smoke for the taste of the smoker. .If a warmer smoke is desired, the cooling sleeve may be abolished entirely, relying alone'on the thermo-syphon cooling of the pipes bowl to cool the smoke sufficiently to make it agreeable for the smoker.

In Fig. 4, it will be noted the bowl end of the union has been modified to make it adaptable as a cigarette attachment 10 for supporting a cigarette, the remaining structure remaining the same so as to make the pipe stem and cooling sleeve interchangeable therewith to form a complete cigarette holder as shown in Fig. 5.
